Tax changes for the 2027 season in Canada: what is new for 2026 returns

Tax changes 2027 Canada filers should know first

The return you file in spring 2027 covers income earned in calendar 2026. So when people search for tax changes in 2027, what they usually need is the list of rules that apply to the 2026 tax year. Most of those changes are already published by the CRA, and a few are still proposals from Budget 2025.

The biggest change is simple: 2026 is the first full year taxed at the lower 14% federal rate. The rate cut took effect on July 1, 2025, so your 2025 return used a blended 14.5% rate. Your 2026 return uses 14% from January to December.

The filing deadline does not move. Most people must file and pay by Friday, April 30, 2027. Self-employed people and their spouses or common-law partners have until Tuesday, June 15, 2027 to file, but any balance is still due April 30. For the full filing process, see our guide to filing a tax return in Canada.

Canada federal tax changes 2026: rates and brackets

The federal brackets were indexed by 2.0% for 2026. Combined with the lower first rate, most people pay slightly less federal tax on the same income than they did in 2025.

Is the lowest tax rate 14% for 2026?

Yes. The CRA's current-year rates page lists 14% on the first $58,523 of 2026 taxable income. Here is a worked example before credits: on $50,000 of taxable income, federal tax at the lowest rate is $7,000 for 2026 (14%), compared with $7,250 at the 2025 blended rate (14.5%). That is a $250 difference before any credits are applied. Our page on the 14% lowest tax rate shows more examples.

Why your credits are worth a little less

Most federal non-refundable credits are calculated at the lowest rate. When the rate falls, each credit dollar is worth less. The 2026 basic personal amount of $16,452 is worth $2,303.28 at 14%. The basic personal amount is reduced for net income between $181,440 and $258,482, down to a minimum of $14,829.

To stop larger claims from shrinking, a temporary non-refundable top-up tax credit keeps a 15% rate on credit amounts above the first bracket threshold. It applies for the 2025 to 2030 tax years and mostly helps people with large claims such as tuition carried forward or big medical bills.

New tax rules Canada 2026: credits and proposals

Budget 2025 announced several measures that start with the 2026 tax year. The CRA's Budget 2025 page, last modified April 17, 2026, still lists the individual measures below as proposed, meaning they need legislation before they can be claimed as described.

• Personal Support Workers Tax Credit (proposed): a refundable credit for 2026 to 2030 equal to the lesser of $1,100 and 5% of eligible earnings. Work in British Columbia, Newfoundland and Labrador and the Northwest Territories is excluded. Details are on our personal support workers tax credit page.
• No double claims for accessibility costs (proposed): from 2026, an expense claimed as a medical expense could no longer also be claimed under the home accessibility tax credit.
• Automatic tax filing (proposed): the CRA would get authority to file a return for certain people, generally those who owe no tax, starting with the 2026 tax year. See automatic tax filing by the CRA.

What ended

The federal fuel charge ended April 1, 2025. The 2025 return was the last year the related fuel charge credit for businesses was available, so it will not appear on 2026 returns.

Registered account limits for the 2026 tax return

The Home Buyers' Plan also changed. For withdrawals made from January 1, 2026 to December 31, 2028, repayments start in the fifth year after the first withdrawal. A 2026 withdrawal has its first repayment year in 2031. Our RRSP contribution limit page explains how the 18% rule interacts with the dollar cap.

CRA account and service changes for the tax return 2026 Canada season

Several service changes took effect in February 2026 and will still apply when you file in 2027. They affect where you find documents rather than how much tax you pay.

1. Digital notices of assessment and reassessment can only be viewed in My Account. If you picked online mail, the notice will not arrive as an attachment anywhere else.
2. CRA account users must have a backup multi-factor authentication option on file. Set it up before tax season so a lost phone does not lock you out.
3. Copies of tax slips can no longer be requested by phone. Download them in My Account or ask the employer or bank that issued them.
4. Individuals owing $1,000 or more can set up a payment arrangement themselves under Manage balance in My Account.
5. The CRA said the NETFILE access code would be easier to find inside My Account.

NETFILE for the current season stays open until January 29, 2027. The CRA then closes it for maintenance before the next season starts. If you are unsure about sign-in, the CRA My Account guide covers the setup steps.
